On Dec. 3, the Federal Bureau of Investigation, the Cybersecurity and Infrastructure Security Agency, and international partners issued guidance on strengthening systems against intrusions by threat actors targeting telecommunications. The guidance was notably informed by recent breaches affiliated with the Chinese government. The recommendations come weeks after the FBI and CISA identified that China-affiliated threat actors had “compromised networks at multiple telecommunications companies.” Initially, the breaches were believed to target specific individuals in government or political roles. However, on Dec. 3, the FBI clarified that these individuals may not have been the intended targets but were instead “swept up” in the operation. T-Mobile was allegedly one of the affected companies. “Threat actors affiliated with the People’s Republic of China (PRC) are targeting commercial telecommunications providers to compromise sensitive data and engage in cyber espionage,” Assistant Director Bryan Vorndran of the FBI’s Cyber Division, said in a press release. “Together with our interagency partners, the FBI issued guidance to enhance the visibility of network defenders and to harden devices against PRC exploitation.” SEE: Live: AWS re:Invent …
